We have performed the largest ever particle simulation of a Milky Way-sized dark matter halo, and present the most comprehensive convergence study for an individual dark matter halo carried out thus…
A common mass scale for satellite galaxies of the Milky Way
- L. Strigari, J. Bullock, M. Walker
- PhysicsNature
- 27 August 2008
New measurements of the velocities of the stars in these galaxies are used to show that they are consistent with them having a common mass of about 107 within their central 300 parsecs, demonstrating that the faintest of the Milky Way satellites are the most dark-matter-dominated galaxies known.
Searching for Dark Matter Annihilation from Milky Way Dwarf Spheroidal Galaxies with Six Years of Fermi Large Area Telescope Data.
- M. Ackermann, A. Albert, S. Zimmer
- PhysicsPhysical Review Letters
- 9 March 2015
The dwarf spheroidal satellite galaxies (dSphs) of the Milky Way are some of the most dark matter (DM) dominated objects known. We report on γ-ray observations of Milky Way dSphs based on six years…
Implication of neutrino backgrounds on the reach of next generation dark matter direct detection experiments
- J. Billard, L. Strigari, E. Mit, KIPACStanford
- Physics
- 20 July 2013
As direct dark matter experiments continue to increase in size, they will become sensitive to neutrinos from astrophysical sources. For experiments that do not have directional sensitivity, coherent…
Constraining dark matter models from a combined analysis of Milky Way satellites with the Fermi Large Area Telescope.
- M. Ackermann, M. Ajello, G. Martinez
- PhysicsPhysical Review Letters
- 17 August 2011
This work presents a search for dark matter consisting of weakly interacting massive particles, applying a joint likelihood analysis to 10 satellite galaxies with 24 months of data of the Fermi Large Area Telescope, and is able to rule out models with the most generic cross section, using gamma rays.
Dark matter constraints from observations of 25 Milky Way satellite galaxies with the Fermi Large Area Telescope
- T. A. C. M. Ackermann, A. Albert, S. Zimmer
- Physics
- 2 October 2013
The dwarf spheroidal satellite galaxies of the Milky Way are some of the most dark-matter-dominated objects known. Due to their proximity, high dark matter content, and lack of astrophysical…
Hundreds of Milky Way Satellites? Luminosity Bias in the Satellite Luminosity Function
- E. Tollerud, J. Bullock, L. Strigari, B. Willman
- Physics
- 26 June 2008
We correct the observed Milky Way satellite luminosity function for luminosity bias using published completeness limits for the Sloan Digital Sky Survey DR5. Assuming that the spatial distribution of…
A COMPLETE SPECTROSCOPIC SURVEY OF THE MILKY WAY SATELLITE SEGUE 1: THE DARKEST GALAXY
We present the results of a comprehensive Keck/DEIMOS spectroscopic survey of the ultra-faint Milky Way satellite galaxy Segue 1. We have obtained velocity measurements for 98.2% of the stars within…
Limits to dark matter annihilation cross-section from a combined analysis of MAGIC and Fermi-LAT observations of dwarf satellite galaxies
- M. L. Ahnen, S. Ansoldi, L. Strigari
- Physics
- 25 January 2016
We present the first joint analysis of gamma-ray data from the MAGIC Cherenkov telescopes and the Fermi Large Area Telescope (LAT) to search for gamma-ray signals from dark matter annihilation in…
SEARCHING FOR DARK MATTER ANNIHILATION IN RECENTLY DISCOVERED MILKY WAY SATELLITES WITH FERMI-LAT
- A. Albert, B. Anderson, R. Wechsler
- Physics
- 10 November 2016
We search for excess γ-ray emission coincident with the positions of confirmed and candidate Milky Way satellite galaxies using six years of data from the Fermi Large Area Telescope (LAT). Our sample…
